After a disappointing end to the season for the San Francisco 49ers, defensive end Nick Bosa expressed concern about defensive coordinator Nick Sorensen's future. Despite showing optimism earlier in the season after an impressive performance against the Los Angeles Rams, Bosa acknowledged a significant decline in the team's defensive output over the last three weeks, leading to doubts about Sorensen's effectiveness.

With coach Kyle Shanahan indicating the need for a change, the 49ers are now on the hunt for their fourth defensive coordinator in as many years. The potential return of former coordinator Robert Saleh, currently with the New York Jets, is a primary consideration, along with other candidates like Dennis Allen and Jeff Ulbrich.
